heat sensor in air cleaner

[1974-318]

Hi,
Im going to be replacing my air cleaner assembly for one without the snout. My question is regarding the heat sensor in the bottom of the air current air cleaner. One tube runs from the snout of the air cleaner and the other to the carb - do I just cap off the port at the carb when I switch over? Will there be any driveability issues doing this or is it just for cold weather/engine startups?
Its on a '74 318, stock motor, carter car if any of that makes a difference
Thanks

I would just cap it off at the carb, unless someones has tee'd into the vacuum source for some other reason. That flap inside the air cleaner is just to draw warm air during cold and damp operation. I had a carb freeze up in the winter when this failed.

Thank you. Is there a cap or cover that I can use to cover the opening on the heat shield where the flex pipe went to?

I'm not sure if that would affect the manifold's ability to shed heat?
